Solid DC
The IOTA SDC1 is a compact yet powerful switch-mode power
supply and battery charger, delivering clean, steady DC power
for 12VDC and 24VDC applications with 120VAC input. The
IOTA SDC1 Series features 15 to 90 amp designs and is
engineered with built-in protection features against AC power
spikes or brown-outs for confident load handling. For superior
battery life maintenance and four-stage charging, the SDC1 is
also available with IOTA’s AmpLife charge control module.
SDC1 SERIES
Keep your batteries in peak condition with the AmpLife AL1
Charge Control Module. The AmpLife programming enables
the Solid-DC Charger to deliver four-stage charging, keeping
batteries fully charged, decreasing charge times, and exercis-
ing batteries to prevent premature failure caused by stratifica-
tion and sulfation of the battery’s plates. The Amplife AL1 is
designed for simple, secure installation and features an LED
indicator for displaying the current charge mode of the SDC1.

CHARGE CONTROL MODULE FOR SOLID-DC CHARGERS
Batteries are charged up to the full-rated output of the SDC1 battery charger, reducing the time needed to charge the battery.
BULK CHARGE
The voltage drops and the batteries are then held for a controlled period at the absorption phase to insure a full and complete charge.
The battery charger delivers a ‘trickle’ charge, maintaining the battery’s full charge and avoiding “gassing” caused by over-charging.
If the battery remains in the ‘Float’ state for seven days, the AmpLife delivers a Smart Charge cycle to dissolve sulfate layers and to avoid stratification.
The AmpLife AL1 Charge Control Module is the easiest, safest way to keep your
batteries fully charged and in peak operating condition while maximizing useful life.
By utilizing the AmpLife programming, IOTA SDC1 chargers automatically deliver a
four-stage charge cycle to your battery system. Whether you need frequently-cycled
batteries charged quickly and efficiently, or are maintaining stored batteries in top
condition, AmpLife charge control provides the assurance that your batteries will
perform when you need them to.

FUNCTION
DIMENSIONS
The LED indicator on the AL1 informs the user of the SDC1 charging state and the
battery charge status. When first activated, the AL1 will read the number of cells
in the battery and indicate the voltage of the battery through a series of flashes.
Refer to the chart on the right for LED code indications.
After reading the battery, the AL1 will initiate either a Bulk Charge phase or Float
Charge phase depending on the battery’s charge status. When the AL1 is in the
Bulk Charge mode, the green LED indicator will flash rapidly (approx. 2 flashes
per second). When the Bulk Charge is complete, the AL1 begins the Absorption
Charge and the LED indicator will flash at a slower rate (approx. 1 flash per sec-
ond). If, when first activated, the battery is not in need of charging, the AL1 will
enter the Float Charge phase and the LED will remain lit (no flashing).
